The study measured not just how long recruiters looked at a given resume, but what elements of a resume merited the most, or least, of their attention, Augustine said. From this data, what Augustine calls a "heat map" was created, showing a resume's cold spots and hot spots.

Recruiters spent 80 percent of their time on the following "hot" details, in descending order:

Name

Current title/company

Previous title/company

Previous position start and end dates

Current position start and end dates

Education

The rest of what you provided -- the stuff about your coaching Little League, the handsomely-shot photo of you -- you might just as well have skipped.

"We were especially surprised about the photos," Augustine told ABC News. There are venues, she said, where having a photo might work to your advantage -- in some online self-promotion, you might want visitors to click on it. But on a piece of paper, she said, all a photo does is consume precious few seconds of attention that should be going to your qualifications for the job.

A photo doesn't tell a recruiter if you're qualified or not. Plus, plenty of recruiters won't even look at resumes with photos, she said, since to do so can leave them liable to charges of gender, age or race discrimination.

"You want your information to be organized," Augustine said, with the most important stuff (the items listed above) high up. Unless you're a recent grad, put your education last.

Bullet points are fine, but use them sparingly -- to draw attention to only the most important items. Dense blocks of text make it hard to digest information quickly, so avoid them.

Less is more, Augustine said. Your resume should be just an "elevator pitch" -- you key strengths, put succinctly, framed by plenty of white space.
